Walmart/Sam's Club for obvious reasons.
All Proctor & Gamble products - Crest, Ivory soap, Oral-B, Scope, Pantene and Vidal Sassoon, Tide laundry detergent, Bounce dryers sheets, Pringles, Bounty and Charmin paper products, Iams pet food, Gillette razors, Duracell batteries, Pampers, Folgers coffee and about a "bazillion" (

) other things. They make so many things that I basically check the back label on every consumer product I'm not 100% sure of. Just can't support the #1 animal testing company on the planet.
